9 Claims.

This invention relates to a wall assembly or construction. 7

It is an object of the invention to provide a lightweight, fire-resistant wall that is relatively inexpensive and easily assembled and that requires only a light structuralframing, with no closely spaced vertical studs, for example. Other "objects and advantages will appear from the detailed description that follows.

The invention comprises a supporting substructure, a corrugated sheet forming a part of the exposed face of the finished wall, a lightweight thermal insulating and preferably resiliently compressible sheet disposed behind the facing and in front of v(outside) the substructure, and suitable L means securing the said sheet to the substructure.

The invention comprises, also, a wall assembly, of the kind described, including means extending over the upper edge of the corrugated sheet for preventing the entrance of water between the said sheet and a member of plane surface disposed behind the said sheet.

A preferred embodiment of the invention is illustrated in the drawing, and the invention will be exemplified by description in connection therewith.

Fig. 1 is a. vertical sectional view of a wall constructed in accordance with the invention.

Fig. 2 is a longitudinal sectional View 2-2 of Fig. 1.

Fig. 3 is a longitudinal sectional view across a vertical joint between facing elements of the wall.

There is shown a supporting substructure including columns it, as, for instance, I-beams spaced far apart, say 20 feet or so. i

Horizontal members or girts are secured to th columns, as by spot welding at positions! 2. Each of the horizontal members may suitably include two elements it, whose faces lie in the plane of the heel: of the wall sheet assembly it and another element it that is secured to the substructure and to which the elements it aresecured. The element it extends from the substructure and slopes dovmwardly in a forward direction, and at its outer edge, extend-s below the level of the top edge of the said sheeting and terminates preferably, in a downwardly extending flange it The well sheeting includes as sbaclring elemerit, an appreciably resilient, lightweight. thermal insulating sheet of the type of a fibre board, as, for instance, a sheet of felted wood or cane fibre commonly sold as insulating lumber, also, a sheet comprising composited and stifiened alternating plies of corrugated and plane-surface asbestos paper, or the like. This lightweight sheet on line should be shape-retaining and. adapted to withstand substantial compression without collapse or a great decrease in the thickness.

The outer sheeting 18 of the Wallis corrugated, strong, water-impermeable, and resistant to buckling or denting under pressure or shock.

The wall may include, for some purposes, a

substantially rgid and strong sheet I9, of generally plane faces, disposed on the back of the insulating sheet H and suitably secured thereto as by casein, a phenol formaldehyde'condensation product or other suitable adhesive. This sheet i9 is held firmly in contact with the substructure, by means that will be described. Also, the wall contains preferably a waterproof lining material 20, as, for instance, an asphaltimpregnated roofing felt or other flexible waterproof sheet, disposed continuously between the corrugated facing and the lightweight sheet it. I may use for the sheets l8 and I9 sheets of 001m pressed asbestos and Portland cement and similar compositions, steel or ceramic ware. However, the asbestos and Portland cement composition is preferred, because of its lightness, minimized tendency to buckle, resistance to elevated temperatures, and small Weight for a given strength and stiffness.

The wall sheets are secured to the substructure as by such means as a bolt 2!. This bolt is preferably provided with a non-corrodible exterior of the head 22 and of the tapered shank 23 It may be constructed as described in U. S. Patent 2,021,929, issued to me on November 26, 1935. Thus, the head and also the shank of the bolt adjacent to the head may be lead-covered.

At its threaded end, the bolt engages a suitable clip or hook 26, which, in turn, engages a pro jecting element or other part of the substructure, as, for example, a flange 25. The tapered. shank of the bolt fits snugly in a preformed hale in the 3 corrugated facing sheet.

When the nut on the bolt 2! is tightened, the corrugated facing is drawn firmly against the inwardly disposed sheets ll and this sheet, or the sheet t9, if used, against the substructure. Because the facing contacts over a very small part only of its total area with the backing terial, the pressure is concentrated along cer tain narrow zones and a tight and non-rattling assembly is promoted.

' Also, there are defined spaces 26 between ccnvolutions oi. the corrugated facing and the fibre or other backing element. These spaces permit drainage, in'a downward direction, ct any water 'of the panel. Here the corrugated facing extends above the top edge of the lightweight backing sheet H, by an amount approximately equal to the height of the strip 21. The'flashing strip contacts at its back firmly against an element of generally plane surface secured to the substructure and constituting, if desired,a part of the substructure. At its face, the strip conforms to the back of the top portion of the corrugated sheet, as illustrated.

Entrance of rain water into theinsulating sheet at the bottom thereof is prevented by a flashing member 28 which may consist of flexible, waterproof, thin sheet of asphalt-impregnated roofing felt or the like, extending vertically between the facing and the backing and also outwardly and under'the lower edge of the corrugated facing.

The wall sheets suitably rest at the bottom, uponthe top of the downwardly sloping portion of one of the projecting elements l5. the element thus forming a drainage sill or ledge below the panel. 1

At the top of the sheets. 'on the other hand, they fit. below the lower face of an element 15 and may be flashed thereagainst by the strip 21.

Here, the element l5, extending completely over the upper edge of the'sheets, shields the structure against entrance of rain, by forming a drainage platform thereover.

The wall sheeting described may be preassembled as a panel and supplied to the fabricator asone unitary article. However, I prefer to preassemble only the sheet l9 and the insulating board l1, as by means of one of the adhesives described, and then apply the waterproof liner 20 and the facing i8 as the whole is being assembled tering holes in. the several layers of sheeting and water-tightness, the sheets may be so arranged in the clip and the nuts are tightened on the bolts, so that the assembly is made permanent. For the purpose of giving greater assurance of in the assembly that the vertical joints between sections of the corrugated facingv ID are nonregistering, as illustrated, for example, in Fig. 3.

The lightweight backing sheets may meet in flush relation, as shown at the joint 29, whereas the corrugated facing sheets may overlap, as at position 30, there being used the preformed flashing strip of kind described in my said patent to close snugly the joint or the space between the corrugated facing and the plane surface of element l3.

Using such a construction, there may be constructed a wall weighing much less than heretofore constructed walls of equivalent strength and fire-resistance and costing, for instance, only about two-thirds as much as a brick wall.

This wall assembly may be used as either an outside or inside wall with equal facility. a It will ,be understood that the details given are for the purpose of illustration, not restriction, a d that variations within the spirit of the invention are intended to be included in the scope of the appended claims.
